Overview
Activated calcium is a specialized form of calcium that undergoes surface modification to enhance its reactivity and functional properties. Unlike regular calcium, it features a larger surface area and improved dispersibility, making it valuable for industrial processes. It is commonly produced through mechanical or chemical activation methods. This material is widely used in B2B sectors, including water treatment, metallurgy, and agriculture. Its high reactivity allows it to serve as a cost-effective alternative to other alkaline agents, particularly in applications requiring rapid chemical reactions.
Physical and Chemical Properties
Activated calcium exhibits unique physical and chemical characteristics due to its modified surface structure. It typically appears as a fine white or grayish powder with a density of around 1.55 g/cm³. Its melting and boiling points are consistent with elemental calcium at 842°C and 1484°C, respectively. Chemically, it reacts vigorously with water, releasing heat and forming calcium hydroxide. This property makes it useful in applications requiring quick alkalinity adjustments. It is also soluble in acids, facilitating its use in chemical synthesis and pH regulation processes.
Main Applications
In water treatment, activated calcium is employed to neutralize acidic wastewater and remove heavy metals through precipitation. Its high reactivity ensures efficient treatment with lower dosages compared to conventional lime. In metallurgy, it acts as a flux to remove impurities during smelting processes. The agricultural sector utilizes it as a soil amendment to correct acidity and supply calcium nutrients. Additionally, it serves as a reagent in chemical manufacturing, particularly in producing calcium-based compounds.
Safety and Storage
Handling activated calcium requires precautions due to its exothermic reaction with water. Workers should wear gloves, goggles, and respiratory protection to prevent skin contact or inhalation of dust. Storage must be in dry, airtight containers to avoid moisture absorption, which can degrade quality and cause hazardous reactions. Spills should be contained and cleaned up using dry methods, avoiding water to prevent heat generation. Proper ventilation is essential in storage areas to minimize dust accumulation and associated inhalation risks.
B2B Procurement Guide
When procuring activated calcium, businesses should prioritize suppliers with certifications for quality and safety standards. Key specifications to verify include purity (typically 90-95%), reactivity rate, and moisture content (ideally below 1%). Bulk purchasing often reduces costs, but storage capabilities must align with material stability requirements. Sample testing is recommended to confirm performance in specific applications. Lead times and logistical considerations, such as moisture-proof packaging, should also be factored into procurement decisions.
